Open the condom into a flat sheet and l
49、ay it on asmooth, flat surface suitable for cutting thin films. Cut thespecimens with a single impact of the die. The cutting edges ofthe die shall be free of nicks. After cutting, the specimensshould be visually examined, preferably using a stereo micro-scope to look for flaws. Record the direction orientation of thespecimens. Report separately data from specimens cut atdifferent orientations.A2.5.2 If dressing materials are present, remove by care-fully wiping the sample with a clean dry cloth or tissue beforemeasuring the thickness.A2.5.
